At a conference the international ice core science community discusses the latest developments in their field.

For his Master’s project, architecture student Jeremy Morris assessed the life cycle of building materials in Vaud Canton. His research shows that the construction industry could shrink its carbon footprint by making more regular use of soil. Morris proposes three courses of action, which he will present at the Quinzaine de l’Urbanisme.

In the extremely dry summer of 2018, beech leaves discoloured in many places as early as July. Now, studies by the Swiss Federal Institute for Forest, Snow and Landscape Research WSL show that up to 10% of these trees died - a multiple of the natural mortality rate. The summer of 2022 is likely to have further affected beech trees in dry locations.

Researchers from ETH Zurich are studying how alpine vegetation is responding to a warming climate – and how some plant communities are continuing to stand firm against newcomers from lower elevations.

For over 25 years PSI has been conducting an uninterrupted series of measurements on the Jungfraujoch, studying the impact of aerosols on our climate at 3,580 metres above sea level. The measurements are taken in the Sphinx Observatory, the landmark building on the Jungfraujoch, inaugurated in 1937. This is Europe’s highest research station that can be reached throughout the year via the legendary mountain railway, the Jungfraubahn.

The smallest of all plastic particles have remained largely unexplored until now, because they could not be detected in the environment. Now researchers at Eawag show: Nanoplastics stick to slimy biofilms, which can for example be found on stones in streams or rivers. When freshwater snails feed on the slime, the nanoplastics are taken up.
